Whole Foods in Harbor East closed for several hours Sunday afternoon after a man robbed the store, a spokeswoman for the supermarket said.

Kate Malloy, Whole Foods' public relations manager for the mid-Atlantic region, said no one was hurt and the store in the 1000 block of Fleet St. was closed as a precaution while police investigated.

The store reopened around 6 p.m. Sunday, according to a post on the market's Facebook page.

Police spokesman Det. Jeremy Silbert said a man entered the store about 2:30 p.m. Sunday and demanded money from an employee at one register. The man implied he had a weapon though it was unclear if he actually had one, police said. He fled on foot with an unknown amount of money, Silbert said.

Silbert described the suspect as a 30- to 35-year-old man of mixed race with a light beard, wearing a black bandana, blue and white shirt and blue jeans. After the robbery, police slowly let out customers who were in the store after questioning them for about 10 minutes to find witnesses. Kelly Stegman, marketing team leader for the store, said it was unclear how many customers were inside when the crime occurred.

"Everyone's ok, that's the important part," she said, as employees huddled together near an entrance while a police crime scene technician worked inside searching for evidence.

A note posted on the front of the store read: "We are closed today until further notice. We hope to open our doors shortly, but have to take precautions to ensure the safety of our team members and customers. Thank you for understanding."
